Answer:

  x ≈ -0.5416

Step-by-step explanation:

As with any "solve for ..." problem, you essentially want to "undo" what has been done to the variable of interest. Here, if you were to evaluate the left-side expression (where the variable is) for some value of x, you would ...

You want to "undo" these operations in reverse order. That is, you work from the bottom of this list toward the top, using inverse operations along the way.

The inverse of addition is subtraction; the inverse of multiplication is division. The inverse of raising to a power is taking a logarithm.

undo add 5

  [tex]2\cdot9^{10x+7}+5-5=70-5\\2\cdot9^{10x+7}=65[/tex]

undo multiply by 2

  [tex]\cfrac{2\cdot9^{10x+7}}{2}=\dfrac{65}{2}\\\\9^{10x+7}=32.5[/tex]

undo raise to a power (take logarithms)

  [tex](10x+7)\log(9)=\log(32.5)\\\\10x+7=\dfrac{\log(32.5)}{\log(9)}\quad\text{equivalent to $\log_9(32.5)$}[/tex]

undo add 7

  [tex]10x+7-7=\dfrac{\log(32.5)}{\log(9)}-7\\\\10x\approx -5.41562[/tex]

undo multiply by 10

  [tex]\dfrac{10x}{10}\approx\dfrac{-5.41562}{10}\\\\x\approx-0.541562\\\\\boxed{x\approx-0.5416}\quad\text{rounded to 4 dp}[/tex]

Answer , 95!!

Step-by-step explanation:

Answer:

0.27 lt/s

Step-by-step explanation:

80 liters in 5 minutes

5 minutes are 300 seconds (5x60)

We know how many seconds we need to fill up the tank (300 seconds for 80 liters). Now we need to know how many liters we can fill up in 1 second, as the question requires "liters per second".

80 lt / 300 sec

X lt / 1 sec

80 x 1

----------    = X

300

X = 0.2666666...

X = 0.27 lt / s

Step-by-step explanation:

The specifications of a decagonal pyramid would be the following

It has one face that is a decagon.

35 diagonals in the base.

10 isosceles triangles as faces above the base

11 vertices - 10 in the base and 1 at the top

20 edges - 10 in the base and 10 above the base

This can all be seen in the picture of the decagonal pyramid below. The only decagonal face is on the base of the pyramid as the top is a vertice where all of the triangles meet.

Answer:

~B,D,E~

Step-by-step explanation:

Answer: the correct answer would be B

Step-by-step explanation:

The increase is by 11 dollars an hour so b is your answer.

Answer:

12

Step-by-step explanation:

Since the entire line is 60 and MN is five times as long. Then I would say that you could just divide 60 by 1/5 or 0.2

since the length of the line is 60 you gots to fos and divide it my homie.

60/5=12 so thats means the length is 12

you got that my guy

Answer:

I got 17.99 inches

Answer:

18 ft (it's correct)

Step-by-step explanation:

formula for volume: volume = [tex]\pi r^2h[/tex]

plug in the values that they give you

5,652 = [tex]\pi 10^2h[/tex]

simplify

5,652 = 100pi h

solve for h

[tex]\frac{5652}{100\pi } = h[/tex]

h = 18 (rounded)

The answer is D. 6.5

Answer:

96

Step-by-step explanation:

Hello There!

The following figure shown is a parallelogram

If you didn't know opposite interior angles of a parallelogram are congruent

Therefore the angle that has a measure of 96 degrees and the angle labeled 2 are congruent

hence ∠2=96

Answer:

42.5

Step-by-step explanation:

Cut this up and the rectangle at the top has an area of 9*3.5 = 31.5. The triangle in the bottom left corner has an area of 2, the square has an area of 4 and the bottom right triangle has an area of 5.

Add these values up to get 42.5

Answer:

33

Step-by-step explanation:

An easy way to do this is create a proportion.

[tex]\frac{18}{6} = \frac{x}{11}[/tex]

Keep in mind you could also write this equation as  [tex]\frac{6}{18} = \frac{11}{x}[/tex] as long as you are consistent. The number of calls should be in the same place and the hours should also be in the same place (either the numerator or denominator).

Next, just cross multiply.

6x = (18)(11)

6x = 198

x = 33 calls

Answer:

They would get 33 calls!

Step-by-step explanation:
